Abstract:

Ride-hailing systems, car- and bicycle-sharing networks, trip-planning apps and other innovative services that capitalize on advances in mobile communications, cashless payments and remote monitoring are increasing in popularity around the world. Users appreciate — and in many places have grown to depend upon — the convenience and flexibility these services offer at a range of prices.

New mobility services have the potential to complement public transit, but they could also lead to worsening traffic congestion, more vehicle accidents, additional air pollution and other unwelcome effects if not managed carefully.
